PCHP · Personal Consent Handshake Protocol

Privacy you can verify

The open protocol behind every consent request in 🤫 One. Nothing about you is shared without your yes, and every yes leaves a receipt.

The handshake

Every exchange, the same four steps

  1. Step 1

    Prove who you are

    Like SSH for people. Identity is proven without handing over the secrets behind it.

  2. Step 2

    Agree what is shared

    What, why, and for how long. You decide in plain terms.

  3. Step 3

    Share one field

    Exactly what was agreed, nothing more, encrypted end to end.

  4. Step 4

    Keep a receipt

    Both sides sign it. You can read it forever and revoke it any time.

What it guarantees

Enforced by the protocol, not promised

  • Stays on your device

    The server only ever holds data it cannot read.

  • One field at a time

    Never a bulk copy. Never your whole profile.

  • A receipt every time

    You see who read what, and why.

  • Never sold or tracked

    No cookies, no trackers, no training on your data.

Works with what exists

A consent layer on the rails agents already use

MCPA2AAP2UCP

PCHP adds identity, consent and a receipt on top. It does not replace them.

Open, not owned

Published for anyone to build to

PCHP is RFC-001, under an open license, with no patent claimed on the core handshake. Next, in design: RFC-002, where websites subscribe to the preferences you choose to share.

Consent is the whole point

Every request, scoped to one field. Every yes, on a receipt only you can read.
